Be it known thatI, FRED E. Kurze, a citizen ofl the United States,-and resident of Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful "Improvements in La dles, of which the followingis a specification.

This invention relates to ladle cars, and

:more particularly to hot metal ladle cars used to transport molten metal around foundries, blast furnaces and the like.

One object of this invention is to provide a ladle of the class described, the shape o which Vis as close to' aj sphere as is practical to make, and, therefore, the radiating surface is reduced to a minimum.

`Another object Vis to provide acar having 'the top or 'upper section of the 'ladle so shaped that the opening'through which the metal is poured will be reduced to a minimum, and the sides of said section will overlie the molten metal, thereby reducing the area of molten metal exposed directly to the atmosphere, thus lessening the coolingof the metal and also reducing the possibility of the metal splashing from the car.

Another ob]ect is to provide a car having the ladle so that the center of gravity is considerably lower than that.- of the customary inverted vfrustrum of a cone type ladle, and S, turn over on a defective car should be derailed.

A4 further-objectis to providea hot metal ladle car having the novel construction, de-

shaped track, or in case the described, and illustrated in the accompanyin drawings.

n the drawings, Figure 1 is a top planoi a car constructed in accordance with my invention.

Figure 2 is -a side elevation, hand half of which is sectioned along Ythe lon 'tudinal center line of the car.

lgure 3 is an end elevation of the car. Figure 4 is a transverse sectional 'elevation on the line IV-IV of Figure 2.

Referring more particularly to the drawings,' the numerals 2 and 3 designate the trucks of the car,

' able construction and which support a body frame. 4 having a central depressed' portion 5 and ladle supports 6 and 7. Couplers 8 are attached to the frame 4 inthe usual manner to provide for the connecting of the -car with a locomotive orto other cars.

, faces of the supports' and 7. Each o therefore,`less. liable to p about the axis of either and combination of parts hereinafter4 the right 17 which may be of any suit- A ladle of substantially or nearly spheriy cal contour is mounted on the ladle supports 6 and 7. The ladle comprises .a substantially hemispherical bottom portion -9, a cylindrical central portion 10, vand a rustoconical top portion 11 having an open upper end forming a contracted opening or port 1 2. 4The ladle is of the usual construction and comprises a metal shell 14 lined with a layer of suitable refractory material 15.

Trunnion supporting members 16 are securedon diametrically opposite sides of the f ladle,

and are provided with horizontally spaced trunnions 17 mounted in suitable bearing depressions 'or seats 18 in the u per the members 16 also carries a lifting .trunnion 19,'the axis of which is materially above the horizontal axis of the ladle, and in vertical alinelnent therewith. The trunnions 19 are adapted to receive the lifting chains from a crane or other overhead supporting device,

lwhereb the ladle maybe lifted from the car bo y for tilting. It will be readily apparent that with the trunnions 1'9 located above the horizontal axis of the ladle, accidental tilting of the ladle is prevented.

The Vtrunmons 17 are adapted to support and steady the ladle during the travel of the car, and are also used to support the ladle when it is desired to tilt it on the car. The trunnions 17 are so arran ed that the ladle .may be tilted to either si e of the car pair of the alined trunnions 17 at the-opposite sides.

Suitable tilting lugs 21 are secured to the cylindrical portion of the ladle body at diametrically. opposite sides of said portion from said trunnions. The lu adapted to receive lifting chains orI the like and to tilt the ladle about the trunnions 'Those skilled in the m to which my 'mvention belongs will readily a preciate the advantages to be gained by a ot metal car constructed 1 11v accordance with `my invention. The molten metal willhave a mim- `mum amount of exposure to the atmos here, the likelihoodv of splashing is reduc to a minimum, the center of gravity is lowered, and the novel shape which closely approximates a sphere reduces the radiatin'gsurface of the ladle to a minimum.
